It’s the day after Reformation Day. All the Luther and Calvin costumes are at the dry cleaners; the left-over party treats have been taken to the office; the post-Protestant hangover has set in. It’s as good a time as any to take a second look at what really divides us from our Roman Catholic friends, family, and neighbors. After all, Pope Benedict seems to have a soft spot for the Apostle Paul and Martin Luther–maybe we’re not so far apart after all?

At least one ELCA Lutheran thinks so and asked plaintively at the First Things blog why he couldn’t receive communion at the local parish church. In response, Anthony Sacramone detailed a few of the outstanding issues that still divide Lutherans (and the Reformed) from Rome. Here’s a preview:

Let’s cut to the chase: would the Roman Catholic Church today accept as doctrinally true the Lutheran teaching of the alien righteousness of Christ, of the great exchange of His righteousness for our sin, of our sanctification as being in Him, even though we are called to good works — but for the sake of our neighbor and not in aid of increasing our justification? If not, again, who are these Lutherans Reverend Saltzman is talking about whose differences with Rome are now of little significance?

Do these Lutherans now accept the existence of a Treasury of Merits? Or has Rome admitted that this was a bankrupt medieval invention and is now, in the interest of ecumenicity, disposable? Have indulgences, the flashpoint of the Reformation, also become irrelevant?

I ask this honestly: what is the true nonnegotiable here?

Let’s discuss the papal office for a moment: Was Pope Urban II Infallible, “evangelically understood,” when he declared, in regard to the First Crusade:

“If anyone who sets out should lose his life either on the way, by land or by sea, or in battle against the infidels, his sins shall be pardoned from that moment. This I grant by right of the gift of God’s power to me.”

Did the bishop of Rome have this authority? Urban II is addressing men who are off, he hopes, to kill the enemies of the Faith and to retrieve stolen property. Is this the true nature of the power of the keys as described in the Gospel of Matthew? Does this notion of dying in a holy war and going straight to Paradise sound familiar?

Here’s another question: Does the pope have this same authority today—to proactively forgive the temporal punishment for sins that would otherwise send someone to Purgatory (or to a purgative state), thus promising them a straight ticket to heaven in the event they died trying to kill someone else? I’m not interested in whether or not it is likely to be exercised in this day and age, nor whether the Muslims in the 12th century invited this response for overrunning the “Holy Land.” I’m only interested in whether Benedict XVI, by virtue of his office, has this authority, given him from Christ.

Whether the pope is infallible in matters of faith and morals is inextricably tied to how justification is construed. The same can be said for the nature of the Eucharist, and the priesthood.

What is the wedding garment without which no one enters the wedding feast of the King? Is it something of our own, dry-cleaned, purified, and bleached? Or is it the gift of Someone else? Is it something we do to ourselves, by aid of grace? Something we endure, in the sense of suffer? Or is it something we receive, like the Eucharist, from Another?

For some, the alien, imputed righteousness of Christ is a legal fiction, and Luther’s image of the dunghill covered with snow is usually cited as evidence. And yet these same Christians have no problem with the transfer of the supererogatory merits of the saints to the accounts of the properly disposed.

The merits of Christ’s sacrifice transferred to the sinner, as a sinner, is a fiction, but the merits of Josemaria Escriva transferred by dint of papal proclamation — that’s real.

Really?

The issue remains the same today as on October 31, 1517.

The entire thing is worth reading.
